Raymond Ye Mr. Pettibone IB Physics 2 November 2013 Internal Assessment DESIGN Aspect 1: How does the time a rubber band spends stretching a force of 12.5 N affect the force required to break/snap the rubber band? IV- The time spent stretching the rubber band 12.5 N DV- The force required to break/snap the band Units for Independent Variable- Minutes Units for Dependent Variable- Newtons Aspect 2: Variables that will be kept the same include: -The force of the stretch -Conditions

How to make the best airplane in the world Step 1 Start with an A4 paper or remove 19mm of a standard US letter (8 1/2 x 11) paper. Fold the top right corner to the left side edge. Use the folding tool to nail the creases and unfold. Then repeat the same steps with the left corner. Step 2 Take one side and lay it against the crease leaving 1 to 2 millimeters of space between the side of the paper and the crease. Then open the paper and do the same with the other side. Take both sides

Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed

2.4 Galileo Galilei: Sixteenth-Century “New Scientist” 1. In your own words explain why Albert Einstein considered Galileo to be the “father of modern science” Albert Einstein considered Galileo to be the father of modern science because of how many of Galileo’s discoveries have become the basis of today’s science. 2. Why did Galileo choose to use a ramp to perform his acceleration experiment? Technology during Galileo’s time was still quite primitive. His experiment which required him to drop

Behind The Crimes Free will is part in of our own responsibility. It’s part of our conscious mind‚ our choice‚ to complete certain task‚ or game. On a criminal justice point of view however‚ a felony or a crime. Our actions are determined not by other people but our own state of mind. The classical and neo-classical theory states that “all individuals have free will and makes all their own choices in life based upon this free will.” (Aberle 46) people know what they are capable of‚ and they use

SAMPLE PROBLEMS: 111-SET #1 VECTOR ADDITION‚ SUBTRACTION 01-1 1). A man is able to row a boat at 3 mph in still water. If he rows his boat pointed straight across a river with a current of 4 mph‚ what is his net velocity? If the river is 0.5 miles wide‚ at what point will he land on the other side? Solution: The first step in problem solving is to identify the problem type. In this problem we are asked for a ‘net velocity.’ Since velocities behave as vectors‚ then we have a vector addition

Therefore the sum of all the energies in the system is a constant. TMEinitial=TMEfinal 3. Explain the basic ideas that govern the design and operation of a roller coaster. A roller coaster is operated and designed through the application of Physics. The law of Conservation of Energy governs the changes in a coaster ’s speed and height. Simply put‚ the higher an object is off the ground‚ the more potential energy it has - that is‚ potential to gain speed as it falls. As it falls toward the ground

L. Morano are leading an end-of-the semester trip aimed at exposing motivated students in the Natural Sciences to the diverse career opportunities available to them. This 6-day‚ 5-night program in New York City will expose students to a unique‚ behind-the-scenes look at an array of careers and allow students to experience the type of science involved with each career. During the trip students will meet with professional scientists at a variety of research‚ teaching and government institutions
